Intel 22nm 'Ivy Bridge' Core i7 3770K Reviews

It's still the best performing client x86 architecture on the planet and a little to a lot better than its predecessor depending on how much you use the on-die GPU.

and whether you’re a regular user or an enthusiast. If you are still using an LGA1366 system, and it’s not overclocked to at least 4.0GHz,
Ivy Bridge is worth a look if you want some new toys. Not only are you getting a very hefty stock performance improvement,
but native support for USB 3.0, SATA 6Gb/s, PCI-E 3.0, better overclocking, and much lower power consumption as well.
If you are building a system from scratch, Ivy Bridge is easy to recommend for most people.
If you bought a cheap dual-core Core i3 as a temporary solution until Ivy Bridge was released,
then by all means a quad-core IVB processor is going to be a terrific upgrade.
However, if you own an i5-2500K or i7-2600K/2700K switching to their Ivy Bridge counterparts is not going to give you a lot of extra bang for your buck.

So seems like 3570/3770K tops out @ 4.5-4.7GHz for 24/7 on air which seems to correspond around 4.8~5.1GHz Sandy Bridge, what does 2700K and 2500K do on average you'd say at ~1.35v? While Ivy brings some new stuff, it hardly seems worth it picking up a Ivy over SB if you're just a 24/7-use air clocker especially if you're a lucky US citizen living near microcenter where I think they sell 2500K @ $199 if I'm not mistaken which is probably $50 cheaper than what 3570K will be at launch at say newegg. For $50 cheaper 2500K seems like the better deal in that case (I see what Ivy Bridge offer is just worth aprox $25 higher cost).

Intel always sends ES chips for release-date reviews. AFAIK, those who got the press pool chips all received E1 (retail) stepping chips. The pre-launch leaks were about half and half E0 and E1. From people that have clocked both, I don't think there was a huge difference really.

When Mercedes brought their C111 to Talledega years ago and blew away the closed course record did it count? Yes..
That was a "factory" car and a "one of" that no one could buy and was never sold.Records are records and that is a fact so get over it.

fair enough - didnt' realise that most reviews on ES chips - thought that reviewers would be provided retail samples - I mean they've been in the supply chain quite a while no ?

"The fact of the matter is that everything Charlie has said on the big H is correct. Haswell will be a significant step forward in graphics performance over Ivy Bridge, and will likely mark Intel's biggest generational leap in GPU technology of all time. Internally Haswell is viewed as the solution to the ARM problem"

Sorry, can't answer the why; it's just the way it has always been - we always get ES chips. In my meager experience from Lynnfield up through Ivy, Intel always sends ES chips with their press kits. For the most part they are always retail stepping chips that happen to be ES. I think some 980X's back in the day were different but aside from that it has been pretty consistent.

I dont think Ivy bridge is all it could have been, its a good tick and that is about it. I mean its a improved sandy bridge i dont get why everyone sees it as a strong release? At 3-4% IPC improvement the CPU has limited improvement the only thing really improved is the GPU performance so it stands good enough against AMD's A8 3500m's but Trinity will wipe the floor with this in the mobile gaming space.

That's kind-of the point though, isn't it? (A good tick.) Haswell is where the iGPU is going to do better for Intel. AMD still has that one in the bag. 3-4% IPC increase is pretty solid for a tick; it is the same micro-architecture after all.

Ivy is a good upgrade for those that waited through Sandy. If I already had SB and used a discrete GPU (as most XS patrons do), I'd stick with SB. Otherwise Ivy is a solid next step.

Performance improvement over 2600K is around 10%.
It runs a bit hotter but nothing to worry about.
Upgrade from Sandy=No.
Upgrade from any other platform (minus LGA2011)= Get ivy instead of sandy.
Need to use IGP= Get Ivy or AMD APU.

Power draw is low compared to Sandy Bridge (about 25W at stock clock and 15-20W after OC), but temperature not. After OC @ 4,7 GHz temperature reaches 90C. This is 12C more than Core i7-2700K @ 4,5 GHz at the same vcore and colling solution.

this part really interests me

either the sensor is not calibrated right,
or theres bad contact between the chip and IHS
or the chip itself just dosnt spread out heat very well (this could simply be caused by being smaller while drawing similar power)

we know that the core is very long, i wonder if pressure on the IHS was lowered to prevent damage.
